My impression is that Elsevier is a company locked into the past by a couple of decades. The leadership that I spoke with seemed to have worked in publishing for a very long time. And, probably because of that, they had an old-school publishing mentality with regards to how to reach their customers, provide value, and create revenue.
I sensed that many in the technology team seemed frustrated with their leadership. They had new visions for how to evolve the publishing model to reflect the rise of sci-hub and changes in the industry. However, they were stymied by a very bureaucratic, well-entrenched, and siloed organization.
I expected that the leadership would have some strategy for dealing with this, but it seemed like they were aloof, probably grown fat from decades of near-monopoly. They had a net profit margin of 37% in 2017! Talk about a business ripe for disruption.
Elsevier has been around a very, very long time (wikipedia says 1880), and it shows. I can't imagine getting anything done within that company. So, it's no surprise that some of them are finally leaving to try out a new model. Let's hope for the best.
